A review on the effects of low atmospheric pressure on plant cultivation in space: The study of physiological responses and adaptive mechanisms [PDF]

open access: yesعلوم، فناوری و کاربردهای فضایی
Plants are the main components of the bioregenerative life support system in long-term space missions to Mars. To cultivate plants in the Martian conditions, it is necessary to understand how they adapt to low atmospheric pressure.

A review of nanoparticle decharging in atmospheric pressure plasma afterglows

open access: yesFrontiers in Physics, 2022
Plasma afterglows interacting with dust grains present a dynamic environment in which negatively charged dust grains leaving the plasma bulk experience an environment with plasma conditions transient in space and time.

Influence of atmospheric pressure change on gas sampling in mine closed area

open access: yes矿业科学学报, 2020
The variation of atmospheric pressure will cause the exchange of air volume between the closed area of the mine and the external environment, which will have an impact on the gas migration in the closed area of the mine.In order to study the influence of

Photoactive thin silver films by atmospheric pressure CVD [PDF]

open access: yes, 2008
We report the visible and UV activity of thin silver films. The films are grown using a CVD process employing aqueous-based silver precursors, flame-assisted chemical vapour deposition.

Where do winds come from? A new theory on how water vapor condensation influences atmospheric pressure and dynamics

open access: yes, 2010
Phase transitions of atmospheric water play a ubiquitous role in the Earth's climate system, but their direct impact on atmospheric dynamics has escaped wide attention.

Impact of atmospheric noise on observing the slichter mode

open access: yesGeodesy and Geodynamics
Atmospheric pressure fluctuations can result in long-period noise (T > 10 s) in gravity observations, and it is crucial to remove the atmospheric pressure effect for observing weak dynamic signals using superconducting gravimeters.

Open air plasma deposited antimicrobial SiOx/TiOx composite films for biomedical applications

open access: yesCurrent Directions in Biomedical Engineering, 2016
Open air atmospheric pressure plasma jet (APPJ) enhanced chemical vapour deposition process was used to deposit biocompatible SiOx/TiOx composite coatings. The as deposited films are hydrophilic and show visible light induced photocatalytic effect, which
